Abstract

Un método para la lixiviación de un material que contiene uno o más metales objetivo usando una solución ácida de lixiviación para extraer dichos uno o más metales objetivo, dicho método incluye: determinar empíricamente un rango de concentración óptima de ácido para dicha solución ácida de lixiviación, como sigue: (a) determinar la relación entre la concentración del metal(es) objetivo extraídos y el consumo de ácido en dicha solución de lixiviación, (b) utilizar dicha relación para evaluar los parámetros de valor para el material que contiene el metal objetivo en función de dicho consumo de ácido, y (c) determinar dicho rango de concentración óptima de ácido, que es el rango de pH que corresponde a un parámetro de valor óptimo; y (II) controlar la concentración de dicha solución ácida de lixiviación de tal manera que su pH este sustancialmente en el rango de concentración óptima de ácido en todo el material.A method for leaching a material containing one or more target metals using an acidic leaching solution to extract said one or more target metals, said method includes: empirically determining an optimum acid concentration range for said acidic leaching solution, as follows: (a) determine the relationship between the concentration of the target metal (s) extracted and the acid consumption in said leaching solution, (b) use said ratio to evaluate the value parameters for the material containing the target metal based on said acid consumption, and (c) determining said optimum acid concentration range, which is the pH range that corresponds to an optimum value parameter; and (II) control the concentration of said acidic leaching solution so that its pH is substantially in the range of optimal acid concentration in the entire material.
